Aluminum reacts with chlorine gas to form aluminum chloride via the following reaction: 2al(s)+3cl2(g)→2alcl3(s) what is the maximum mass of aluminum chloride that can be formed when reacting 32.0 g of aluminum with 37.0 g of chlorine? express your answer to three significant figures and include the appropriate units.

An electric kettle uses electrical energy to boil water. energy from the electricity is transferred to the water, heating it up. an electric ice maker also uses electrical energy, but it freezes water to form ice. since energy can’t be created or destroyed, and water loses potential energy when it freezes to form ice, what happens to the energy put into the ice maker and the energy released by the water?

One of the most common causes of inaccurate melting points is too rapid heating of the melting point bath. under these circumstances, how will the observed melting point compare to the true melting point?
